Lightroom (and photoshop) has a limited temperature range which means that the raw files always look red even if
you have calibrated the white balance correctly in the camera.
Setting the white balance should firstly be done by taking a picture of a patch of grass, i save a few of these on the memory card
to start with you need to download the DNG profile editor from Adobe, this can be found
here.
Step 1: open up an image in lightroom, for this example i have used the white balance image, then click on Library and select "Convert to DNG"
Step 2:
after installing the profile editor, open the DNG Profile editor and then open up the image that you have converted to a DNG file
Step 3:
Click on the Colour Matrices tab and change the temperature slider right down to -100, this will set the mid temperature of your raw files to be alot less than normal which
will give you alot more room around the cooler temperatures to work with.
Step 4:
You can also use this profile to set the white balance, i select the lightest area of the image which will generally give you a light brown white balance
Step 5:
Once this is done you can save the camera profile, call it something like
Canon 5Dmk2 IR base
Step 6:
Open Lightroom (if it was open then restart) and choose one of your infra red images and open it up in Develop.
Step 7:
on the right hand side where you have the
tools like meta data, at the bottom of these boxes there is a box called Camera Calibration, open this and select your newly created profile from the dropdown at the top of the box.
This may do something wierd to the image, dont worry, just scroll back to the top and you will see that the white balance temperature slide may have moved, slide this further down until you get the image that you want.
Its a good idea to try to get your raw image looking as close to the JPEG image as possible, this should give you a good base to do any monochrome or colour changes to it.
Once you are happy with these settings, you can save this as a preset by clicking the (+) next to presets and saving it as "infrared preset" or something, then you can use this to apply the profile to images in your library.
